    • An MPI(Message Passing Interface) communication method in a system level which supports a private IP through modified hole punching in a grid environment is provided to modify hole punching so as to be executed at an MPI program in order to solve the problem that an existing MPI program cannot be executed on a private IP cluster. In a communication method using MPI programs which respectively are executed at a plurality of clusters on the basis of grid middleware, a modified hole punching process to grant a private IP address and a public IP address to each MPI program is presented so that direct communication can be achieved between MPI programs. In this case, each MPI program acquires its own public IP address from each management node's NAT(Network Address Translator) service. Each MPI program, acquiring its own public IP address, delivers channel information, which contains its own private IP address and the acquired public IP address, to the other MPI programs. Each MPI program stores the delivered channel information in an identification table correspondingly.
    • 提供了一种在网格环境中通过改进的孔冲孔支持专用IP的系统级MPI(消息传递接口)通信方法来修改打孔,以便在MPI程序中执行,以便解决存在的问题 MPI程序无法在私有IP群集上执行。 在使用基于网格中间件分别在多个簇执行的MPI程序的通信方法中,呈现了向每个MPI程序授予私有IP地址和公共IP地址的修改的打孔处理,以便直接通信可以 在MPI程序之间实现。 在这种情况下,每个MPI程序从每个管理节点的NAT(网络地址转换器)服务获取其自己的公共IP地址。 每个MPI程序获取自己的公共IP地址,向其他MPI程序提供包含其自己的私有IP地址和获取的公共IP地址的频道信息。 每个MPI程序相应地将传送的频道信息存储在识别表中。
